How can different CAT5/6 cables affect sound.
While is is beyond doubt that analog cables affect sound quality and SPDIF, TOSlink and AES/EBU can effect SQ, depending on the buffering and clocking of the DAC, I am at a loss to find an explanation for how different CAT5 cables can affect the sound.
The signals over cat5 are transmitted using the TCP protocol. This protocol is error correcting, each packet contains a header with a checksum. If the receiver gets the same checksum then it acknowledges the packet. If no acknowledgement is received in the timeout interval the sender resends the packet. Packets may be received out of order and the receiver must correctly sequence the packets.
Thus, unless the cable is hopeless (in which case nothing works) the receiver has an exact copy of the data sent from the sender, AND there is NO timing information associated with TCP. The receiver must then be dependent on its internal clock for timing.
That is different with SPDIF, clocking data is included in the stream, that is why sources (e.g. high end Aurenders) have very accurate and low jitter OCXO clocks and can sound better then USB connections into DACs with less precise clocks.
Am I missing something as many people hear differences with different patch cords?

@herman Excellent summary of Chat GPT. I am reposting so people can take this to heart: No AI is yet capable of an original thought. "ChatGPT doesn't "claim" anything. It finds things on the web related to the topic, summarizes it, and repeats it. It does not have the intelligence to separate fact from fiction especially in such a technical area. Experts can't agree, it is silly to think AI can sort it out." |
The AI Summary that Google is often quite useful in that it creates a summary of all the stuff that it has found online about the search terms. As a consequence the response must be contemplated critically, and the response is sometime head spinning in that adjacent sentences may state something and its negation. A fundamental principle of logic is, symbolically, ∀ A (~(A&~A)). Unfortunately today, critical thinking is, in medical terms, in a critical state. |
@unsound yes indeed it should! Thank you for the link, I hadn’t looked at it in I don’t know how long. Funny, this entry:
